How can I change the time/date settings on Windows 8 and avoid affecting the game?

We would like to bring your attention to the fact that changing system clock time or date affects the game. It is not allowed to do while playing the game as can help to get an unfair advantage.
In order to avoid such situations we strongly recommend you to set system date/time in the following way:
1. Close the game completely when you want to change the settings: drag the app to the bottom of the screen, and hold it there until the app flips over.
2. Perform the changes using the Time Zone option. If you set date/time manually it will affect the game and you will receive a warning message.
3. Open the game again only after you complete all the changes.
